Answer 2

Volume of Cone:

1/3 Bh where B is the area of the base

1/3 Bh = 5
Bh = 15
B = 15/h


The cylinder has the same base area as the cone.

Volume of Cylinder:

V = B*h

B = V/h and B = 15/h

The height of the cone and the cylinder are the same.

V/h = 15/h

Volume of Cylinder = 15.

Answer 3

Its b

Answer 4

Its A.

Answer 5

@Dredge u know its b

Answer 6

lol @linaboo123 hows it b tho??

Answer 7

i have a smart math teacher

Answer 8

It's A. -.-

Answer 9

@SmokeyRiver that v=1/3bh is the formula for the volume of a pyramid, why do we use it here?
